1 INTRODUCTION The following cost estimates are considered planning level estimates used for determining the

cost of various alternatives. The estimates demonstrate the relative cost to one another. The

estimates are not intended to identify final projected cost of the project. A further defined cost

estimate based on the selected alternative will be developed in the future.

Cost estimates were developed for Options B, C and D that considered dredging, placement

area construction, shore protection, site management, lands easements rights of ways and

relocations (LERRs) engineering and design, and supervision and administration. Each option

divided the channel from river mile 5 to mile 36 into 10 segments in addition to the Bar Channels

for which the costs were estimated. The costs for each cycle over the 20 year term of the

DMMP were adjusted for escalation per 1110-2-1304 Civil Works Construction Cost Index

System. While these planning level estimates were made to primarily provide an order of

magnitude cost of an option and an annual estimated funding requirement, they also provide a

basis for comparison of the options. An overall 15% contingency was applied to all estimates

for the first 5 years and 20% for the remaining years due to the breadth of uncertaintainties

surrounding the options and the advice of the ITR process. Fuel costs were estimated at $3.76

per gallon for off-road diesel as of May 2009. South East Labor and Benefit rates for the Local

25 southern dredging union were used to establish unit costs, production, and rates. Alternative

B, the Recommended Plan, is estimated at a total of $788 million. Approximately $628 million is

estimated for Mile 5 to 36 and $160 million for the Bar Channel Sections. Alternative C is

estimated at $800 million. Approximately $640 million is estimated for Mile 5 to 36 and $160

million for the Bar Channel Sections. Alternative D is estimated at over $1 Billion over the life of

the DMMP and has been eliminated from further consideration as a viable plan.

The cost estimates and assumptions listed in this Appendix have been used to evaluate and

compare the costs for each alternative.

The estimates prepared under this appendix have been used in the DMMP for the cost estimate

as the separable items relating to cost sharing, and operation and maintenance are more easily

separated.



Tables D-1 to D-3 provides a summary of the costs for all three options by year, river reach and

site. The amounts in the tables also indicate the cost sharing values for elements per law and

policy at the time the estimate was made.

2 GENERAL BASIS OF ESTIMATE AND ASSUMPTIONS 2.1 Placement Areas (CDF’s) • Costs do not have as much variability or uncertainty as the Beneficial Use sites. Costs

are based on considerable experience with numerous projects supported by historical

data from the Corps. There is assumed little or no environmental issues or mitigation

requirements affecting costs or implementation.

• Site Management costs are for minimum required efforts to insure that there is sufficient

dry material for dike raising needed to support the schedule and meet capacity

requirements. Initial efforts are repeated over 2 years to compensate for poor existing

site conditions and provide better stability and more available material for dike raising.

Following subsequent dredged material fill events, a single year effort is applied.

• Rehabilitation includes perimeter and interior ditching to obtain dry material for dike

raising. Second lift dike raising assumes site management has been done in the interim

and sufficient dry material is available and therefore does not include any ditching.

• Typical dike sections include 3:1 slopes and a 12 ft crown width. Dikes will be

constructed/raised by side-casting material from the site interior.

• The dikes on the lakeside of CDFs 17, 19, 22, and D/E will be constructed with a 25’

crown and 4:1 side slopes.

• Dike raising (initial and second lift) does not include any grassing or other stabilization.

These costs are considered to be relatively minor.

• No interior training dikes are included, only perimeter containment dikes are constructed

or raised.

• Site dimensions were estimated from aerial photos.

• Weir costs are current pricing data from USACE, Mobile for 16 ft (4 each, 4 ft long bay)

weirs, 8 feet tall, including outfall pipes, installed; $35,000 each.

• Due to wet conditions, dikes are constructed in two lifts; the total width of the 20-year

dike is constructed in the initial construction to provide long term settlement and

consolidation.

• Dike volume calculation for the bottom half of the 20-year dike: first sequence calculates

the area of the trapezoid, and then compresses the area under the crown and 1/2 of the

side slope length, simulating the "iceberg" effect of a displacement dike.



• Two passes on a perimeter dewatering ditch around the exterior and one interior pass of

the rotary ditcher is included in the initial rehabilitation costs. Perimeter ditches all

around the site are included in the initial effort. Perimeter ditches are shortened to two

dike lengths for subsequent events to new weirs.

• The second lift volumes assume the site is managed in the interim; the material is dried

and available as a result of management.

• Side-cast borrow costs are based on current costs of $3.50/cy that includes side-casting,

dressing and grassing where usable materials may be present adjacent to or near the

existing dike alignment.

• In areas where longer haul efforts are required and the possiblility of double or triple

handling materials is required to achieve the dike template, the CY unit costs increase to

$6.00 and $8.00 per/cy. This occurs on PAs 17, 19, 22, D/E.

• Side slopes for the dike are based on slope stability analyses and qualitative reviews of

shear vane tests as discussed in the Geotechnical Report Appendix.

• Costs assume dredged material placed strategically around the site to provide dike

stability and width for haul roads.

• The estimated remaining capacities of the CDFs subtract 2 feet for required site

freeboard and 1 foot for ponding. For example, a site with 4 foot of remaining freeboard

was estimated to have 1 foot of available dredged material capacity.

2.2 Beneficial Use Sites • Costs have variability and uncertainty due to site conditions and access impediments,

possible marsh dike stability issues, owner requirements and adjacent property impacts.

Planning, engineering, permitting, access and coordination efforts could also be greater

than estimated.

• Site management, planting or other habitat restoration efforts are not included; nor is

removal or degrading of marsh containment dikes upon completion.

• Site dimensions were estimated from aerial photos and property maps.

• Available capacities (based on property acreage) were reduced by a third to a half to

allow for open water areas and circulation in the marshes.

• Typical marsh dikes are assumed to be constructed to a height of 5-7 feet, using

adjacent side cast borrow at an estimated unit price of $55/lf.

• Typical site preparation does not include water control structures.

• Pipeline lengths were scaled from aerial photos from center of reach to center of site.

Unit price to lay and remove shore pipeline was estimated at $12/lf. Unit price to lay and

remove marsh pipeline was estimated at $16/lf.

2.3 Hydraulic Dredging Costs • Dredging cost estimates are supported by historical prices for the region and by Corps

data. Costs were estimated by developing production tables for various dredge plant

configurations as applicable for the various site conditions and locations. Booster pump

costs and mobilization/demobilization are included in the unit prices for dredging.

Dredging costs were developed for 27 and 30 inch discharge hydraulic cutterhead

dredges operating alone or utilizing 1 or 2 booster pumps depending on the pipeline

lengths required for placement. Production estimates were produced utilizing data and



information from the Corps and dredging contractors as well as software systems

specifically designed for estimating dredging production that consider pump size and

power, dredge material characteristics and other factors. Operating and ownership

costs including overhead, bond and profit were developed from data and information

obtained from the Corps and dredging contractors for dredges that could be reasonably

be expected to bid and perform the work resulting from implementation of the DMMP.

For the CDF dredging costs, pipeline costs were assumed in the mobilization and

demobilization as most of the CDFs used are adjacent. For BU costs the pipline costs

were added.

Table D-6, Hydraulic Cutterhead Dredge Cost and Production Analysis, details the analysis and

assumptions made to determine the dredging and pipeline costs.

DMMP/SIES ALTERNATIVE COST ESTIMATES FOR COST COMPARISON October 2010


2.4 Shore Protection Costs • Traditional shore protection costs are based on top elevation of 8 ft, a bottom elevation

of -2 ft, side slopes at 3:1, with an application of 0.27 tons/sf/lf at $80/ton resulting in a

unit cost of $640/lf.

2.5 Alternatives B and C Cutterhead Dredging • General: Total volumes include non-pay excess dredging quantities. Pay volumes in

estimate are reduced by dividing by 135%. Historical volumes used were from the 1995

to 2005 dredging contracts for all reaches except Reach 30-36, the Turning Basin, and

Clooney Island Loop, which did not include 2005.

• General: Costs include 10% Engineering and Design, 8% Supervision and

Administration for Construction and 15% Contingency for the first five years of the plan

and a 20% contingency thereafter. A contingency is applied to cover minor variations

and incidental costs through the planning, design and construction phases. This is not

intended to cover variations in market factors such as dredge plant supply and demand,

inflation fluctuations, spikes in fuel costs, etc.

• Reach 34-36: The channels are dredged on a 10 yr cycle. The Port/Non-federal quantity

of 88,000cy is dredged every 5 years.

• Reach 30-34: Costs for Site 7 are split with Reach 26-30. DAMP is applied at Site 7 in

years 0 and 1 due to wet existing conditions, in preparation for Rehabilitation and dike

raising in year 3.

• Reach 26-30: Costs for Site 7 are split with Reach 30-34. DAMP is applied at Site 7 in

years 0 and 1 due to wet existing conditions, in preparation for Rehabilitation and dike

raising in year 3.

• Reach 21-22: Shore Protection is applied along the channel side of sites 15 and 16N.

• Reach 16-21: Shore Protection and Rehabilitation of Sites 17, 19, and 22 would likely

take 2 years and should be initiated in year 3 to be ready to accept material in the

combined site in year 5. The DAMP at the Foreshore Dike site is applied only for 1 year

initially, as opposed to the typical 2-year application, since the site is new and the initial

placement will not be much above the water table. Subsequent applications following fill

events are also applied for 1 year only.

• Reach 12-16: Expansion of Sites D and E would likely take 2 years and should be

initiated in year 3 to be ready to accept material in the combined site in year 5. The

DAMP at the Foreshore Dike site is applied only for 1 year initially, as opposed to the



typical 2-year application, since the site is mostly new and relatively dry and

consolidated. Subsequent applications following fill events are also applied for 1 year

only.

• Reach 9.5-12: No DAMP or Shore Protection is applied in this reach since only non-

adjacent Beneficial Use sites are utilized.

• Reach 5-9.5: Utilizes a combination of CDF rehabilitation and levee raising with

beneficial use.

2.6 Alternative D – Hopper Dredging • Reach 34-36, Reach 30-34, Reach 26-30, and Reach 22-26 are the same as in

Alternatives B and C. Offshore disposal is not cost effective above Mile 22 because of

the excessive travel distance to the disposal area.

• Dredging costs are based on a typical rental contract rate of $1,600 per hour. Hourly

rates are based on historical prices from New Orleans and Mobile District hopper rental

contracts and include Mobilization/Demobilization allocations.

• Rental Costs include hopper dredge, survey vessel, survey plots and silent inspector

telemetry.

• The estimate is primarily based on cycle time including dredging, travel to offshore

disposal area, unloading, turning and return to dredging reach.

• Total time for dredging, unloading, and turning offshore is estimated to be 45 minutes.

Due to the curvature in the channel through the Devils Elbow reach, the dredging time

was increased to 1 hour.

• The distance to the offshore area is estimated at 7 miles beyond the channel entrance

(Mile 0).

• Travel time to the disposal area is based on a typical loaded speed of 10.89 mph.

• Travel time to return to the dredging reach is based on a typical unloaded speed of

11.88 mph. The return time includes travel to turn around at Devils Elbow (Mile 23).

• An allowance of 1.1 hours was added to account for wait time for LNG traffic in the

channel.

• A typical hopper dredge capacity of 6,300 (Eagle, now Terrapin Island and the Glen

Edwards) cubic yards is used. This includes a reduction of 100 cubic yards to account

for residual material after unloading.

• A load factor of 58% was applied to convert gross capacity of the hopper to the effective

volume of dredged material.



• An efficiency factor of 95% was applied to the operating time to account for traffic,

fueling, maintenance and repairs.

• The quantity of material to be dredged is the same as the quantities evaluated for

Options B and C for purposes of comparison and calculation of costs and comparison of

options.

4 BAR CHANNEL The Bar Channel ranges from Mile 0 to approximate Mile -30 where it meets the natural deep

contour of the Gulf. Approximately 7 to 8 million cubic yards are dredged and agitated semi-

annually on an as needed basis, typically through a rental contract. An average of 6.7 million

cubic yards per year has been agitated in the channel and an average of 700,000 cubic yards

per year have been placed in the ODMDS annually. To determine the preliminary costs for

maintaining the Bar Channel, the average yearly cost over the last 5 years was determined at

$4.6 million. The costs were adjusted using a 10% Engineering and Design, 8% Supervision

and Administration and 15% Contingency for the first 5 years and 20% for the remaining years.

The costs for each cycle over the 20 year term of the DMMP were adjusted for escalation per

1110-2-1304 Civil Works Construction Cost Index System.

DMMP – Revised Plan B Calcasieu River and Pass, Louisiana Cost Narrative

Tetra Tech 1 September 2010

Dredged Material Management Plan (DMMP) Calcasieu River and Pass, Louisiana

Cost Narrative 1. Project Description

A. General: The Calcasieu River and Pass, Louisiana, project spans 36 miles from Lake

Charles, Louisiana, to the Gulf of Mexico, and 32 miles offshore. The Calcasieu Ship Channel handles about 50 million tons of cargo every year. The existing dredged material disposal capacity is not adequate for maintaining the channel over the long term. Existing disposal sites are at or near capacity. Other disposal sites have been lost to commercial development. The DMMP identified areas for the placement of dredged material for the 20-year life of the project.

B. Purpose: The purpose of the DMMP is to develop a plan for the placement of material

dredged from the maintenance of the Calcasieu Ship Channel, and anticipated improvements for the next 20 years.

C. Design Features: To prepare the disposal areas to receive the dredged material, site

rehabilitation, dike raising, dike construction, shore protection, and site management will occur. The various disposal area placement sites are shown in the project’s site plan which is included in Appendix A.

2. Basis of Estimate

A. Basis of Design: “Calcasieu River and Pass, Louisiana, Dredged Material Management Plan,

Appendix D – Cost Estimates,” dated February 2008. “Calcasieu River and Pass, Louisiana, Dredged Material Management Plan,

Supplemental Environmental Impact Statement, Volume I,” dated May 2008. B. Basis of Quantities: The estimate is based on the overall quantities for Revised Plan B

provided by the designer. The overall quantities are presented in Appendix B. The quantity estimates include loss factors as listed below: Dredge Material Pay Volume Reduction 35% Dike Construction Shrinkage 15% to 40%

3. Design, and Construction Schedule

Sign PCA February 2009. Initiate Planning, Engineering, and Design February 2009. Advertise August 2009. Initiate Construction October 2009. Complete Construction October 2029.



The estimate is based on construction and operation and maintenance occurring over a 20-year period. The tentative project schedule and implementation schedule are presented in Appendix C.

A. Overtime:

Typical construction, crew (1 shift) working 12hr/day, and 7 day weeks.

Typical dredge construction, crew (2 shifts) working 12hr/shift/day, and 7 day weeks.

B. Construction Windows: Continuous construction activity is anticipated. 4. Contracting Plan The dredging portion of the project will likely be contracted to one prime construction contractor. The dike rehabilitation and lifting will likely be assigned to a second prime construction contractor. No subcontractors are anticipated. For estimating purposes, one prime construction contractor was used for the entire project to reflect prime contractor mark-ups only to the costs. 5. Project Construction

A. Borrow Areas: The project is self sufficient in terms of borrow material, except for the

rock shore protection. B. Construction Methodology: The construction activities proposed at the various placement

sites include site rehabilitation, and initial dike raising (RLIFT), active dredging, and placement (PUMP), disposal area management (DAMP), secondary dike raising (LIFT), new dike construction (CONST), and shore protection (SP).

RLIFT includes rehabilitating, and raising existing dikes and installing weirs at confined disposal facilities (CDF). The total width of the dike will be raised during RLIFT. Dikes will be raised by side-casting material from construction activities including perimeter, and interior ditching to obtain dike lifting material. To create the perimeter, and interior drainage ditches two passes will be made around the exterior by a marshbuggie backhoe, and one around the interior by a rotary ditcher. At some CDFs the degrading of dikes will occur. After RLIFT has occurred, PUMP, and DAMP will occur. DAMP construction activities include perimeter, and interior ditching to obtain future dike lifting material. To create the perimeter, and interior drainage ditches two passes will be made around the exterior by a marshbuggie backhoe, and one around the interior by a rotary ditcher. PUMP includes dredging and pumping the material from the river to the placement sites. Dredging will be performed by a 27-inch discharge hydraulic cutter head dredge operating alone or utilizing 1 or 2 booster pumps depending on the pipeline lengths required for placement.



LIFT will not include any ditching as fill material will have been previously made available during DAMP. LIFT is the secondary lifting of the dikes. After LIFT has occurred, PUMP, and DAMP will typically occur again. At locations along the river where no dikes exist, typically beneficial use (BU) sites, new dikes will be constructed. This process is referred to as CONST. These dikes will be 5 feet high constructed using adjacent borrow material with a marshbuggie backhoe an 8-cubic yard (CY) bucket dredge if in marsh conditions . There are two types of SP that will be used: traditional SP will have an 8-foot top elevation, a -2-foot bottom elevation, 3:1 side slopes, and 0.27-tons of rock/square foot (SF)/linear foot (LF). Rock dike SP will have a 6-foot top elevation, a -3-foot bottom elevation, 2.5:1 side slopes, and 0.27-tons of rock/SF/LF.

C. Unusual Conditions: Unusual conditions that might influence construction costs all sites include unusually wet weather conditions, flooding and river currents. Unusual



conditions that might influence construction costs of the beneficial use sites include marsh stability issues, unforeseen owner requirement, and unforeseen property impacts.

D. Unique Construction Techniques: The dredging will be performed by hydraulic

cutterhead dredges with pipelines to the placement sites. The dredge area management ditching will be performed by marshbuggie backhoes and rotary ditchers. The dike construction will be performed by marshbuggie backhoes or bucket dredges depending on the marsh site conditions. The rock shore protection will be placed by barge mounted cranes.

E. Equipment/Labor Availability and Distance Traveled: All equipment is assumed to be

available in the Calcasieu area. Some labor may have to come from other parts of the country.

6. Environmental Concerns

There is assumed little or no environmental issues or mitigation requirements affecting costs or implementation.

7. Effective Dates for Labor, Equipment, and Material Pricing The labor, equipment, and material pricing were developed using the MCACES 2006 English Unit Cost Library, Local 25 Southern Labor Rates, and the 2005 Equipment Library (Region III) for the base estimate. The index pricing data has been prepared in July 2008 dollars. The labor rates from the MCACES 2006 National Labor Library were compared with the current Davis-Bacon Wage rates (General Decision County Index LA20080011, and LA20080015) and actual wage rates (provided by New Orleans District), and Local 25 Southern Rates, Effective Through 30 September 2008 (see Appendix D). The Local 25 Southern Rates are higher than Davis-Bacon Wage Rates. Using current Davis-Bacon Wage Rates may not be appropriate for this market due to the extended period of construction duration in an area that is planned to be saturated with construction activity. Therefore the higher Local 25 Southern Labor Rates were used in the estimate. The higher rates along with the overtime will likely be needed to attract labor to this market. The base estimate has been updated with current quoted fuel prices of $3.76/gal for off-road diesel (provided by the Designer and approved by the Corps), $4.59/gal for on-road diesel and $3.90/gal for gasoline costs in the Calcasieu Louisiana area.

Labor and Equipment Crews Production Output: Production rates for the construction crews have also been estimated based on project conditions. See Appendix E for the Estimated Production Rates and General Assumptions.



8. Project Markups

Escalation: Escalation has been calculated in two steps. Price levels were to be first escalated from effective price levels of the construction cost estimate for July 2008 to an effective price level for October 2008 to match the authorized budget year (FY2009). Since this initial escalation was calculated to be negative based on current OMB data, a zero escalation factor was used per the direction of Walla Walla District Corps of Engineers. Price levels are then escalated again from the budget year to an effective price level for year of construction (i.e. Year 00 price level = October 2009. The escalation cost factors for CWBS Feature Code 12 Navigation Ports and Harbors were taken from EM 1110-2-1304 Civil Works Construction Cost Index System (tables revised 31 March, 2009). Contingency: Contingencies represent allowances to cover unknowns, uncertainties and/or unanticipated conditions that are not possible to adequately evaluate from the data on hand at the time the cost estimate is prepared but must be represented by a sufficient cost to cover the identified risks. A 15% contingency has been used for construction years YR00 thru YR04 to cover design changes and uncertainties in quantities and unit prices. The 15% contingency is based on engineering judgment and ER 1110-2-1302, for a Project/Feature Design Memorandum level project. A 20% contingency has been used for construction years YR05 thru YR19 to cover unpredictable future economic trends as well as design changes and uncertainties in quantities and unit prices.

9. Functional Costs

Functional costs associated with this work were estimated as follows:

A. 01 Account – Lands and Damages: Costs for this account were provided by the U.S. Army Corps of Engineers, and are for Real Estate Costs. Real Estate Costs developed for this plan capture the 1 in 3 rule, which refers to the idea that at least one in every three land owners of both Confined Disposal Facilities and Beneficial Use sites will possibly be unwilling to participate in the disposal of dredged material on their site. These litigation costs have been provided via the Real Estate Plan that was prepared by the New Orleans District Real Estate team.

B. 30 Account - Planning, Engineering, and Design: Costs for this account were estimated at 10% of the construction cost. This account covers the preparation of Plans Specifications and Estimate for construction.

C. 31 Account - Construction Management: Costs for this account were estimated at 8% of

the construction cost. This account covers construction management during the construction contract.



10. Project Cost Estimate

The construction cost estimate was developed using MCACES 2nd Generation (MII) estimating software in accordance with guidance contained in ER 1110-2-1302, Civil Works Cost Engineering. The MCACES construction cost estimate includes the Lands and Damages, Planning, Engineering and Design and the Construction Management costs, however it does not include the project markups noted in Section 8. See Appendix F for the MCACES output report. The Total Project Cost Summary (TPCS) was developed using an excel spreadsheet which incorporates the MCACES construction cost estimate, project mark-ups, and the functional costs.
